I have a problem with oil level in my car. I have consumption about 1 liter for 1K km. This is saying board computer. But I'm not sure if it measures in right way because for example when I stand on one place, BC is showing full oil level. But when measure it during the drive, i shows sometimes 1/4 of the gauge or 1/2 of the gauge... Now I don't know, which statement is the right one.
